Hi ramco To fix the error and avoid the null reference exception, you should check if ActualActionDate has a value before performing the calculation. Here's an updated version of your code: DateTime? ActualActionDate; if (ActualActionDate.HasValue) { ltrlDays.Text = (DateTime.Now - ActualActionDate.Value).Days.ToString(); } else { ltrlDays.Text = "ActualActionDate is null"; }

Assign a valid DateTime value to the ActualActionDate variable before using it in the calculation. Make sure to replace (...) with the code that assigns a valid DateTime value to ActualActionDate. Then, we check if ActualActionDate is not null (ActualActionDate != null), and if it's not null, we calculate the difference in days between the current date and ActualActionDate using the .Value property. DateTime? ActualActionDate = ...; // Assign a valid DateTime value to ActualActionDate if (ActualActionDate != null) { int daysDifference = (DateTime.Now - ActualActionDate.Value).Days; ltrlDays.Text = daysDifference.ToString(); }
